EMIL JAGENBERG, OF DUSSELDORF, GERMANY, ASSIGNOR T0 AMERICAN CAN COMPANY, A CORPORATION OF NEW JERSEY.

MACHINE FOR MAKING NECKED-IN PAPER-BOX BODIES.

Application filed August 27, 1907.

To all whom it may concern Be it known that 1, Earn. JAGENBERG, a subject of the German Empire, residing at Dusseldorf, in the Kingdom of Prussia, Germany, have invented a new and useful Machine for Making Necked-In Paper-Box Bodies, of which the following is a full and complete specification.

The subject of the present invention, is a machine for making boxes of cardboard strips which are glued one over the other. The novelty consists therein, that the strip of cardboard to. be treated is out down at certain places so that one part is wider than the other. The wider part, which goes around the winding spindle or finger first, serves to form the neck and body of the box, while the narrower part, which is ;wound on last, serves to strengthen the body, whereby one or both ends, accordingly as. the strip is narrowed at one or both sides, is reduced, 6. e. is made smaller in diameter than the body, thus providing a'place for the lid, or for the lid and bottom.

In the accompanying drawing: Figure 1 is a side elevation of my improved machine for cutting strips from cardboard; Fig. 2 a plan of the principal part thereof, and Fig. 3 a perspective view. of a box-body formed by the machine. Fig. L is a horizontal section through the movable knives and adjoining 'parts.

The strip a, which is wound into a small roll, is slipped on to the shaft 6 and is carried from here over the guide roller 0 and over the table (Z, i. 6. over the recessed knives e fixed thereon, and under the rising table, or rising and falling U-shaped knives g, which are bent over to an angle and which engage over the ends of the, knives e. The recesses of fixed knives c, are of rectangular shape, while the movable knives g, are rectangular in horizontal section to snugly engage the cutting edges defining said re- 'cesses. When the cutting contrivance is combined with the winding machine, and after a box is completed and while it is being ejected and the strip is at a'stand still, the knives g are depressed and cut the pieces 7 out of the strip.

Suitable means are employed for feeding the paperstrip intermittently, such as intermittently operating feed rollers u, as shown in Fig. 1.

on disk 2' of shaft It actuating the lever is which is connected with a similar lever Z. This lever is connected with the rods on which are fixed to the knives g and are guided in perforations of table (Z. Knives are connected to each other by' a crosshead 79. On the levers is and Z being actuated, the knives are drawn downward and cut the pieces out of the strips. After the cutting process is completed, the knives are drawn 1nto their normal position by a weight or a spring n. The strip is then earned through a glue vat 0, and over the machine, to the winding or bending machine, which is merely hinted at in the drawing, as it does not properly come within the scope of the present invention, and it is then here further treated. The pieces may be cut from one or both sides of the strip.

p The web A is wound on a spindle .9 as shown in Fig. 1.

I claim:

1. In a machine for making necked-in paper box bodies, the combination with guide rollers for a paper strip, of a pasting device to which the strip is conducted after passing the guide rollers, a table, intermittently operable cooperating knives adapted to cut narrow strips from each longitudinal edge of the paper strip, the cut-out portions being spaced apartlongitudinally of the strip whereby the latter, after'passing the knives, is narrower at those portions where the cuts have been made than at other portions, meansfor feeding the strip intermittently, mechanism for operating said knives while the paper strip is at rest, and a winding spindle to'which the paper strip is conducted after passing the knives and pasting device and about which it is adapted to be saidtable,

tanuglar strip from the longitudinal edge of the paper strip; mechanism for operating said sets of knives intermittently to thereby have the cut-out portions spaced apart longitudinally along'the edge of the strip and have the strip narrower insome parts than in others; and a winding spindle to which the strip is adapted to be conducted and wound thereon with the wider portions'of the strip on the inside and the narrower portions on the outside, whereby to form necked-in paper box bodies, substantially as specified.

1 3." A machine for making wound paper necked-in boX bodies Jomprising, in combination: a table over which a paper strip is adapted to be fed; a pasting device to which the. paper strip is conducted after passing the p'a'sting' device being adapted to apply paste continuously to the paper strip; aset of cooperating knives intermittently operable and arranged tocut narrow rectangular strips from an edge of the paper strip with the cuts spaced apart longitudinally along the edge of the strip; mechanism for intermittently operating said set of knives; means for guidingthe' paper strip while passing over-the table and through the pasting device' and-a winding spindle Copies of this patent may be obtained for about whichthe paper strip is adapted to be after passing the, knives, is 'narrower at those portlons where the cuts have been made than at other portions, means for feeding the strip, mechanism for operating said knives, and a winding spindle to which the paper strip'is conducted after passing the knives and about which it is adapted to be wound to fornrneckecl-in paper boX bodies,

the machine comprising means for securing together the convoluted portions'of thepaper strip.
